GRAIN-TRANSPORTING DEVICE.v

SPECIFICATION forming part yof Letters Patent No. 256,319, dated April11, 1882.

Application filed January 12, 1882. (No model.)

To'all whom it mag] concern:

Be it known that I, THOMAS F. HOREN, of Cleveland, in the county ofCuyahoga and State of Ohio, have inventedcertain new and usefulImprovements in Grain-Transporting Devices; and I do hereby declare thefollowing to be a full, clear, and exact description of theinvention,such as will enable others skilled in the art to which it pertains tomake and use the same.

My invention relates to devices for transporting grain, &c., through apipe by means of pneumatic pressure.. A glass pipe is preferred, therebeing no friction, consequently no wear of the grain, which in travelinga great distance would be quite aloss, if allowed to come in contactwith a rough surface. It is designed to place stations at intervals ofabout iifty miles and to force the grain from one station to the other,each station being provided with an elevator and pump, the operation ofwhich will be morefully hereinafter described and claimed.

VIn the drawings, Figure lv represents in side elevation an elevator andpump. Fig. 2 is a front elevation of the same. Fig. 3 represents a valveand parts thereof to be used inv connection with my device. Fig. 4represents a plug that may be used, to force the grain through the pipewhenit is blockaded. Fig. 5 shows the manner of connecting the glasspipe by the usual process of uniting them with a screw-collar.

A represents a grain -elevator preferably' used in connection with mydevice. When in operation this empties the grain into the hopper a.,from whence it passes through thevalves Band B into the pipe C. Thesevalves are operated by means of rods b b', that are attached to thesprings c. and c. These springs are permanently secured to a pillar orany stationary object. They are operated upon by the cams d and d',which are secured to the shaft l). To this shaft are connected the pumpsE and the pulley F. The grain-elevator receives its motion by means of abelt or other suitable mechanism through this pul-` ley F. n

G is an air-tank, which is connected with the pump by means of the pipeg. The air is forced fromfthis tarik into the pipe C. In the rear ofwhere the grain enters the pipe is enlarged,"as shown in C2, so'as toadmit the passage ot' the plug H through an opening in the pipe. Thisopening must be closed so as to be air-tight.

I represents a small pipe that connects with the cylinder-heads ofthevalve B. It ma receiveits pneumatic pressure from the tank G, or from aseparate pump. vIt is adapted to force the grain down the pipeC into thepipe C, and is operated alternately with the valve B, which tapers atits ends, thus operating the" valve h, as shown in Fig. 3.

My device is operated as follows: The pum ps are set in motion by meansof suitable power, transferring the air into the tank G, from whence theblast passes into the pipe C. The elevator now carries the grain to thehopper a, and it passes through thel double valves B and B, which haveareciprocating movement and work alternately with each other. The valveB in closing comes in contact with the pin in valve h, thus allowing theair to pass through the valve Bl as it opens and carries the grainbefore it into the main pipe C. It is then conveyed to the next station,where the grain empties itself into a bin, and is carried by means ofthebuckets into thehopper a, and again goes through the process asdescribed above.

The size of pipe must be proportionate with the amount of air receivedfrom the pumps. If too large, the grain will lie in the bottom of thepipe and only the surface of it will be carried along, and it .willultimately block up the plpe.

When the pipe is blockaded the plug H is inserted into the pipe andforces'the grain along until it reaches the next station.

What I claim is- 1. In an apparatus for transporting grain from place toplace, the combination, with a suitable conducting-.pipe having anenlarged end, of a plug or driver, and devices for feeding grain to theconveyer-pipe, and forforcing ablast of air through said pipe to movethe grain, substantially as set forth.
